Fran 🇦🇷<p>I also managed to stabilize the driver circuit to reduce the oscillations of the light intensity to less than 0.2% (2 mV, 0.84 lumens), from 72% that the original circuit had 😱. The trick was to add four 22 uF ceramic capacitors in parallel to the LED, and another 10 uF at the potentiometer input.</p><p>The goal remains to simulate natural lighting as best as possible, and after all, the sun does not flicker 🤔.</p><p>🧵 <a href="https://mastodon.online/tags/PortuariaLamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PortuariaLamp</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/prototype" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>prototype</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a> <a href="https://mastodon.online/tags/driver" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>driver</span></a> <a href="https://mastodon.online/tags/dimmer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dimmer</span></a> <a href="https://mastodon.online/tags/flicker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>flicker</span></a> <a href="https://mastodon.online/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a></p>
Fran 🇦🇷<p>The design of the dimmable version of the Portuaria is progressing, slowly but it is progressing 🥳.</p><p>Organizing the wiring of the components inside the base was quite a challenge because there are things with fixed positions (potentiometer, LED cable, vertical rod and power plug) and the circuits have to fit into the gaps between those things 🤯. I think it could be simplified more, but for now everything fits into its place.</p><p>🧵 <a href="https://mastodon.online/tags/PortuariaLamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PortuariaLamp</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/prototype" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>prototype</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a> <a href="https://mastodon.online/tags/driver" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>driver</span></a> <a href="https://mastodon.online/tags/dimmer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dimmer</span></a> <a href="https://mastodon.online/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a></p>
